用石墨炉原子吸收光谱法测定了高纯三甲基铝和三乙基铝中痕量Fe、Cu、Mg、Au、Cd和Ga,样品处理安全可靠,测定限在0.1~1μg/g之间。对方法的准确度和产品纯度控制标准进行了讨论。
Trace amounts of Fe, Cu, Mg, Au, Cd and Ga in high purity trimethylaluminum and triethylaluminum were determined by graphite furnace atomic absorption spectrometry. The sample was safe and reliable. The limit of determination was 0.1 ~ 1μg / g . The method accuracy and product purity control standards are discussed.
